IMPROVEMENT IN STEAM-ENGINE OIL-CUPS.

ein tlgrhule tuant tuin tlgrse frttcrf; atrnt mth uniting nrt at tigestmt T0. ALL 'WIIOM IT `MAY C-ONCERN:

Bc it known "that I, F. H, -FURNISS, ot'. Cleveland, in Vthe county ofCuyahogu,and State ofjOliio, have invented a certain new and usefulImprovement in Oil-Cups; and I do hereby 4declare that the following isa full and complete description of' the saine, reference being had tothe accompanying drawings, making a part of this specification, inwhichi Figure l. is a side view of the cup.

Figure 2, a. view of the front.

Figure 3, a. vertical transverse section.

,llikeletters of reference refer to like parts in the several viewspresented.

In tig. l, A` is the cup in which the oil is placed; B, the tube or stemby which it is attached to the pitinan,

cross-head, cranx,l&c., of the machine. At thcupper' end ofthe stem,immediately below the cup, is an enlarge-V mentor chainbcr, C, in whichis fitted a key or plug, D, said plug and chamber being constructed inthe saine manneras :tn rilinary stop-cock, with the exception that theouter end of theplug sl'itted with a screw, E, fig. 3, which penetrates'the ley to the centre ofthe chamber, the purpose of which willhereafterl be shown. F is a. weight suspended by a link, F', from thearm G, and upon which it vibrates between the checks H, fig. 2. Theupper portion of the link 'F' forms a ring-'or yoke, I, through whichy.project the plug and screw above referred to,'in such way as tosurround theratchet-wheel J, secured to the plug, as shown in fig. 1. Tothe inner side of this yoke is pivoted a pawl, K, 2, which falls uponand engages in the teeth of the wheel, and operates the saine as andfora purpose hereafter shown.

Having thnsdescribed the sereral parts of the cup, the practicalapplication and operation ofthc same are as follows, viz;

The cup is supposed to besercwed intothe cross-head of a steam engine,but which may be attached to any other part ofthe machine havingareciprocating movement, or such movement as will cause a vibrationof'the pendulum or weight F. Now it will be evident that as the ball ismade to oscillate by the reciprocating action of the cross-head the plugwill be made to turn bythe action ot' thc pawla'nd ratchet-wheel. ,Ifthe wheel contains twenty toothV then ten strokes of' the piston willproduccone halt' turn ofthe plug, which will bring the transverse porta, iig. 3, which corresponds in size with the bore of Vthe stem, in` anopposite position from that shown in thc drawing, and which beingcharged with oil from the cup, it will ow from -the plug, thence downthe stem into the journal-box or seat, and thus supply it with oil. Newon ten more strokes ofthe piston the port-a will he brought again inrelation to the cup, and from which it will receive a new charge of oil,to be again'discharged through the tube to the journal as before; -andso on, at each revolution ofthe wheel the plug is charged with oil abovefrom the cup, and discharges the same below through the'tube into thejournal-seat, and Vthus it is kept constantly suppliedwith oil by thecontinuous operation of the cup. The purpo'seot` the screw E, referredto, is for gauging the amount of oil to the journal; thus, the plugbeing hollow, its holdingcapaeity will be governed by the distance thatthe screw is'worked into the plug, thus lling the hole more or less, asthe distance that itmay be screwed in or'out. By this means a large orsrnall quantity of oil can be supplied to the journal. The pendulum maybe hung to the plug, and will thus operate in the' manner substantiallyas described. The weight or ball F is hollow, for the purpose of addingmore weight to the pendulum, and thereby cause a more immediatevibration when the action of the engine is slow, or to lighten the samewhen the vibration is rapid, and thus prevent the weight fronrstrikingtoo hardv against the checks H, which are for the purpose of restrictingthe distance of the vibration. l I

What I claim 'as my invention, and desire to secure by Letters Patent,is

, 1. In combina-tion with an oil-cup, a pawl and ratchet, so arranged asto operate the key orplugjofsaid oil-cup, substantially' as set forth.

The pendulumF,ratchet-wheel J, and pawl K, in combination with the plugD, substantially as and 'icr 4 the purpose set forth. Y

3. The gauge or regulating-screw F and plug D, in combination with theoilcupv substantially as and for the purpose described. l
